The former Friends star turns 45 years old today and is hotter than ever. So how is she celebrating?

What we do know is that Aniston participated in The Makers Conference last night in Palos Verdes, Calif., where she interviewed feminist icon Gloria Steinem. During the talk, Aniston talked about women's issues, saying, "Being in the public eye, us women come up against this, that our value and worth is dependent on our marital status and or if we've procreated."

And today, Aniston got a delivery of colorful balloons that were dropped off in the driveway of her L.A. home.

Meanwhile, her fiancé, Justin Theroux, was photographed filming his new HBO show The Leftovers in NYC today. The hunky actor sported jeans, a black jacket and aviator sunglasses with a baseball cap while working outside on the snow-covered streets of the Big Apple.

So are Aniston and Theroux spending her 45th birthday apart?

There was no indication on whether or not Aniston was home today to receive her balloons, so it's totally possible that she's on her way to meet up with Theroux in NYC for some birthday plans.
